The utility model content
For the problems referred to above, the purpose of this utility model is to provide a kind of square steel pipe with ribbing and concrete-filled steel square tubular column with ribbing.
For achieving the above object, a kind of square steel pipe with ribbing described in the utility model, described square steel pipe serve as reasons roll out rib on steel plate ribbed steel by being welded into the band fin steel tube of square.
Preferably, by four block lengths, identical ribbed steel is welded described square steel pipe, or is that a ribbed steel bent jointing forms, or is that two rectangular ribbed steels of bending are welded.
Preferably, the rib on described ribbed steel is distributed on the single or double of steel plate.
Preferably, the rib on described ribbed steel is continuous, or is interrupted, and/or rib is the horizontal parallel setting, or the dip-parallel setting.
Preferably, the identical ribbed steel welding ends separately of four block lengths that described square steel pipe adopts is offered groove, the groove opposite direction of every ribbed steel.
Preferably, the rib spacing on described ribbed steel is more than or equal to 10mm, the high 1.5mm that is more than or equal to of rib.
For achieving the above object, a kind of concrete-filled steel square tubular column with ribbing described in the utility model, by square steel pipe with ribbing, and inject the concrete column formation in this square steel pipe with ribbing, and wherein, described square steel pipe with ribbing is above-mentioned square steel pipe with ribbing.
The beneficial effects of the utility model are:
1, the utility model adopts concrete-filled steel square tubular column with ribbing to replace the conventional steel concrete column, has inherited all advantages of conventional steel concrete column, has the many advantages such as rigidity is large, bearing capacity is high, plasticity, good toughness, easy construction;
2, the utility model adopts concrete-filled steel square tubular column with ribbing to replace the conventional steel concrete column, than traditional concrete-filled steel square tubular column, existence due to rib, strengthened the stability of steel pipe, under certain condition, can relax the flakiness ratio limit value of steel pipe at bearing capacity, reduce thickness of steel pipe, save steel using amount, reduce costs;
3, the utility model adopts concrete-filled steel square tubular column with ribbing to replace the tradition steel core concrete column of putting more energy into, than the tradition steel core concrete column of putting more energy into, because rib is that rolling forms, welding job amount and processing cost have been reduced, can effectively shorten the processing duration, and quality stability is better.

The specific embodiment
Below in conjunction with Figure of description, the utility model is further described.
As shown in Fig. 1-7, the described a kind of square steel pipe with ribbing of the utility model embodiment, serve as reasons roll out rib 2 on steel plate ribbed steel 1 by being welded into the band fin steel tube of square.The utility model adopts square steel pipe with ribbing to replace the tradition steel pipe of putting more energy into, and than the tradition steel of putting more energy into, because rib is that rolling forms, has reduced welding job amount and processing cost, can effectively shorten the processing duration, and quality stability is better.
Described square steel pipe with ribbing, in manufacturing process, carries out steel plate continuous rolling on steel mill's milling train, at rolling surface, rolls out many ribs.
And on ribbed steel, the distribution of rib can have following several situation:
As Figure 1-Figure 4, the rib on described ribbed steel is distributed on the single or double of steel plate.
As Fig. 1, shown in Fig. 5-Fig. 6, the rib on described ribbed steel is continuous, or is interrupted; Rib is the horizontal parallel setting, or the dip-parallel setting.
Due to square steel pipe, on making, no matter be that turnup or bending are all more complicated, so, the ribbed steel complete to rolling further is operating as:
For four ribbed steel welding fabrications:
Four ribbed steels are all offered to groove on welding ends limit separately, wherein the two ends groove opposite direction on every ribbed steel; Four ribbed steels are carried out to adjacent groove face to be adjacent to and to weld together.
Bend the ribbed steel welding fabrications for two:
Two rectangular ribbed steels of bending are all offered to groove on welding ends limit separately, wherein the two ends groove opposite direction on every ribbed steel; Two ribbed steels are carried out to adjacent groove face to be adjacent to and to weld together.
Band fin steel tube after making, according to the distribution of rib, further explain.Establish the steel pipe of rib for single face, rib is positioned at the inner face of steel pipe, also can be positioned at the outside of steel pipe.Rib is positioned at this situation in outside of steel pipe, when building, can add a steel pipe not with ribbing with the fin steel tube periphery.
